PILNG AND TRANSFER APARATUS.

Application filed August 26, 1918.

To all whom i may concern.'

Be it knovvn that', HENRY G. OBRIEN, residing at `Warren, in the county of Trumbull and State of Ohio, a citizen of the United States, have invented or discovered certain new and useful improvements in Filing and Transfer Apparatus, of which improvements the following is a speciiication.

rEhe object of my invention is to provide a piling apparatus for .rolling mills, Whereby blanks may be continuously ieceived from a roll table or other conveyer, evenly piled on top ofv each other, and quickly removed after having been piled. A Jfurther object is to provide an apparatus such as described and which may be adjustedto pile blanks' of different .Widths and lengths.

- ln the accompanying sheets of drawings, which form part of my specification, l have illustrated an embodiment of my'invention. Figure l is a plan vieuT showing the general arrangement of the piling apparatus associated With a roll table eonveyer; Figs. 2 and are sectional elevations taken, respectively, on thelines H-H and lll-Hl, Fig. l; TFig. e a plan vievv of a portion of the apparatus shown in Fig. 3,' and Fig. 5 a detail i sectional vieiv taken on the line V-V, fle"- 3- inthe practice of my invention, l provide, at the end of a conveyer, a horizontally movable table adapted to receive elongated blanks conveyed by the table. Above the table there are-arranged a pair of laterallyspaced plates lying in vertical planes paral lel to the 0feneral line of extent of the conb veyer, the arrangement being such that the conveyer may pass blanks, one after the otlrer, upon the platform betvyeen the plates, Whichr plates cause vthe` blanks to be arranged in an even pile. lt/ieansaie provided for movingr the plate vertically to permit the transfer table to move horizontally after the completion of each pile of blank-s. Pret erably the horizontally movablel table is in the forni of a transfer-table provided with a pair or" tracks adapted to support trucks in alinement with or parallel to the blank conveyei', and a plurality of stub end tracks are arranged at each side of the eonveyer so that,

`While one truck is being loaded, apreviously loaded truck may be removed fromthe transiler table and replaced by an empty truck to be subsequently loaded `When the transfer table is again moved.

My invention, ivhile unlimited to its association with any particular type ot conveyer or to a conveyer for any particular purpose, it is illustrated in connection -with a live roll table comprising a plurality of rolls l driven by means of a motor 2 and the gears and shafts dia graminatically indicatedl rest upon pilingrails l carried by a truck 5,

which truck is movable, by means of a transter table presently to be described, to and from a position at the end ot the roll table. The piler plates are laterally adjustable to receive cut blanks of diderent Widths, and vertically movable to permit a loaded truck 'their loiver edges. is shoivn herein, pairs4 t arms 6 and 6a are attached to the ends of the plates 3. To such arms 'there are secured interiorly threaded sleeves or bushings 7 ivliicli re- .ceive the ends or" oppositely threaded screivs 8 and 8a. For causing the tivo screvvs to turn simultaneously,K they 'are provided with sprockets 9 connected by a chain 10, and to each screv a hand Wheel 'il is attached. That the plates may be held in vertical alinement, they are connected to each other by tivo pairs of toggles comprising laterally projecting links l2 pivoted to the arms G anda, and vertical links lf3 pivoted to the outer ends yot the links l2, as indicated iii Figs. -land 5.

For moving the pilerplates verticall,v,'the

.outer ends oiQ the screvvs and ea are suspended from yokes lil and l5 pivotally mounted on supports or standards lG- and 17, respectively, the yoke l5 being connected to the scievv S by means, ofl 4a link 18 to permit a slight longitudinal movement of the plates 3 when the yokes Ysvving to move llach yoke is pro- Which arms are connected to each other by rod 20, so that the tivo yokes may svving in tothe piler platetff at the properinterval.,

unison. The piler may be counterweighted by means of a-weiglit 2l adjustably Carried A by an arm, 22 secured to the yoke l5.

As will be seen in Figs. i2 and 3, the general arrangement of the piling apparatus is such that the supporting` rails e of the truck 5 are belowthe plane of the roll table. To

roll l of the roll table. The pinch rolls will ordinarily be driven at a speed sutlicient to cause a blank, after it passes beyond their engagement, to slide upon the plate beneath it a sujliicient distance to clear the pinch rolls and their housing. That the ends of the plates forming a pile may be arranged evenly, a suitable adjustable stop 25 may be arranged between the piler plates 3, it being understood that the position` of such stop with reference to the pinch rolls 23 or to the end of the piler plates 3 will be determined by the lengths of the blanks'being piled.

and is movable by a transfer table. As seen in Figs. 2 and 3; the transfer table 26 rests within a shallow pit 27 upon, a track 28 eX- tending at right angles to the roll table. The transfer table is adapted to be' moved from one to the other end of the pit, and hence from one side to the other of the roll table, by means of a motor 29, the driving connections between such motor and tra-ns'- fer table including a shaft 30, beveled -pinions 3l and 32, countershaft 33, pinion 3st, and rack 35 secured to the bottom of the transfer table. 'Un top of the 'transfer table there `are two truck-supporting tracks 36 and 37, as seen particularly in Fig. Q, and leading from the opposite side of both ends o'f the pit 27, and parallel with the general line of ext-ent of the roll table, there are stub-end tracks 38, 39, -liO and 41. Thus, while one truck is being loaded, a previously loaded truck may be removed from the trans` fer table and an empty truck placed on such table in readiness to be moved to loading position. Tt will be seen that the arrange ment of tracks lends itself to the rapid piling of blanks and their quick removal from the vicinity. of the shear.

Tn the .operation of my invention, the

piler plates 3 are first adjusted'laterally to positions depending upon the width of lblanks to be piled. This adjustment is effected by the rotation of one or the other of the hand wheels 1l, which causes the two screws 3 and 3a to turn simultaneously. Also, the adjustable stop 25 may be secured from the receiving end o'f such plates to cause the blanks to be arranged evenly at their ends.

7With zin-unloaded truck 5 beneath the lower edges o f the piler plates 3, the blanks to be piled may be fed one after the other upon the truck until the pile rises to a height approximately level with the meeting plane of the pinch rolls 23. The inner ends of the yokes H and l5 are then raised to cause the piler plates to be liftedabove the top of the pile, after which the motor Q9 is operated to move the transfer table to one end or the other of the pit Q7. Tf the transfer table is in the position indicated in Fig. l, it Will be moved toward the upper end of the pit so that the trac-k 37 on such'table will be in alinement with the tracks 38 and 4:9. ln such osition the loaded truck may be removed, or example on thetrack 38, and an unloaded truck be moved from the track 40 and upon the track 37 of the transfer table. ln this position of the table an unloaded truck previously received from either the track 39' or Ll1 is in a position beneath the piler plates @L3 to have a pile of blanks placed thereon. Thus, by moving the'transfer table alternately from one end As already stated, the truck 5 rests upon l of the pit to the other as the piles are successively formed on the trucks, the loaded trucks may be quickly removed from` the piling position, and a 4practically uninterrupted stream of blanks majT be properly piled and disposed of.

According to the provisions of the patent statutes, l have described the principle and operation of my invention together With the apparatus which I now consider to represent the best embodiment thereof. Howroe ever, l desire to have it understood that,AV

within the scope of the appended claims, my invention may be practised with other forms of apparatus than that particularly shown and described herein. T

I claim as my invention:
